I flew last Tuesday , 2h20min flight on Boeing 737. I was in the middle of the plane ( on the level of wings). No choice of places possible as it was full and places are given in advance..I use earplanes for taking off and landing ( first 15 mins and last around 35 mins..) and foam plugs in the middle of the flight. My app showed not more than 83-85 db during the flight, I can't be sure about the take off..also , the landing was harsh - the plane hit the ground quite violently - could it be very loud ? Cause this time I feel like flobally, on avarage my T is louder since I came back. It was loud after the flight, but I was extremely tired. After a good night sleep it seemed fine, but last two days have been quite loud again and I'm wondering if it can be a post flight spike..the earplanes don't block any noise actually..or very little. I hope they block at least 3 db, that would be already a lot, but I don't put foam plugs for the take off and landing following the main suggestions I read on TT. Now I worry..maybe the take off was as loud as 105 db , fo exaple ? And since the earplugs don't block noise it was enough to cause damage ? Eh..
